Women in space

Women have flown and worked in outer space since almost the beginning of human spaceflight. A considerable number of women from a range of countries have worked in space, though overall women are still significantly less often chosen to go to space than men, and by June, 2020 constitute only 12% of all astronauts who have been to space.^[2] Yet, the proportion of women among space travelers is increasing substantially over time.^[3] The first woman to fly in space was Soviet Valentina Tereshkova, aboard the Vostok 6 space capsule on June 16–19, 1963. Tereshkova was a textile-factory assembly worker, rather than a pilot like the male cosmonauts flying at the time, chosen for propaganda value, her devotion to the Communist Party, and her years of experience in sport parachuting, which she used on landing after ejecting from her capsule.^[4] Women were not qualified as space pilots and workers co-equal to their male counterparts until 1982. By October 2021, most of the 70 women who have been to space have been United States citizens, with missions on the Space Shuttle and on the International Space Station. Other countries (USSR, Canada, Japan, Russia, China, United Kingdom, France, South Korea, Italy) have flown one, two or three women in human spaceflight programs. Additionally one woman of dual Iranian-US citizenship has participated as a tourist on a US spaceflight.

Women face many of the same physical and psychological difficulties of spaceflight as men. Scientific studies generally show no particular adverse effect from short space missions. It has even been suggested by some that women might be better suited for longer space missions.^[5] Studies have continually indicated that the main obstacle for women to go to space remains gender discrimination.^[6][7]
